Abstract

"ENGRENAGEM DE CORRENTE DE ROLETES COM REDUçãO DE PASSO DE CORDA ADICIONADO". A presente invenção refere-se a uma engrenagem de corrente (112) que é definida como incluindo redução de passo de corda adicionada quando em uma condição nova ou "como fabricada". O passo de corda Ps<39> de engrenagem é propositadamente reduzido quando comparado com o passo de corrente Pc como construída (ou um passo de corda de engrenagem máximo teórico) uma quantidade selecionada que é referida neste contexto como "redução de passo de corda adicionada". Esta redução de passo de corda adicionada é adicional à redução de passo de corda inerente que existe decorrente de tolerâncias de fabricação. Uma engrenagem (112) que incorpora redução de passo de corda adicionada é altamente desejada, pelo fato de que ela facilita a extensão do intervalo de tempo de engate para um rolete de corrente associada. A engrenagem (112) é formada de modo a ter um passo de corda que é reduzido em relação a um passo de corda de engrenagem teórico máximo (ou o passo de elo de corrente) em uma quantidade entre cerca de 0,2% e cerca de 1% do passo de corda de engrenagem teórico máximo."ADDED ROPE STEP ROLET GEAR CHAIN GEAR". The present invention relates to a chain gear (112) which is defined as including added rope pitch reduction when in a new or "as manufactured" condition. The gear chord pitch Ps <39> is purposely reduced when compared to the current pitch Pc as constructed (or a theoretical maximum gear chord pitch) a selected amount which is referred to herein as "added chord pitch reduction". " This added chord pitch reduction is in addition to the inherent chord pitch reduction that exists due to manufacturing tolerances. A gear (112) incorporating added chord pitch reduction is highly desired because it facilitates the extension of the coupling time interval for an associated chain roller. Gear 112 is formed to have a chord pitch that is reduced relative to a maximum theoretical gear chord pitch (or chain link pitch) by an amount between about 0.2% and about of 1% of the maximum theoretical gear rope pitch.
